Hi

I have set up a command, and a menu for that command, that displays when an
editor of a certain type is opened. This works. When I open the editor, I
see the enabled command, when I close the editor, the command disappears.

When I click away from the editor and focus on another area of the
workbench, I want the button to disappear or be disabled. This isn't
happening at the moment.

I am controlling the visibility through the visibleWhen on the menu, to an
activeEditorId.

What you have done seems to be right. Please raise a bug with a sample
code to reproduce it: http://bit.ly/NewBugInPlatformUI

You probably want activePartId (which will only be the editor ID when
the editor has focus).
